What is famciclovir (Famvir)?

Famciclovir is an antiviral drug. It slows the growth and spread of the herpes virus so that the body can fight off the infection. Famciclovir will not cure herpes, but it can lessen the symptoms of the infections.

Famciclovir is used to treat infections caused by herpes viruses, including genital herpes, cold sores, shingles, and chicken pox.

There is no cure for herpes and famciclovir will not prevent you from developing symptoms in the future.

Famciclovir may also be used for other purposes not listed in this medication guide.

What is the most important information I should know about famciclovir (Famvir)?

Take this medication for the entire length of time prescribed by your doctor. Your symptoms may get better before the infection is completely treated.

Treatment with famciclovir should be started as soon as possible after the first appearance of symptoms (such as tingling, burning, blisters).

Herpes infections are contagious and you can infect other people, even while you are being treated with famciclovir. Avoid letting infected areas come into contact with other people. Avoid touching an infected area and then touching your eyes. Wash your hands frequently to prevent passing the infection to others.

Genital herpes cannot be cured; however, there are medications that can be prescribed to treat outbreaks and minimize the symptoms.

  • Genital herpes is extremely widespread, largely because it is so contagious. Carriers can transmit the disease without having any symptoms of an active infection.
  • At least 45 million Americans are infected with the genital herpes virus, with approximately one million new infections each year.
